Brief Description of our Research Interests
We are interested in understanding the origin, nature and consequences
of the interactions of physical systems with their environment.
These questions are particularly challenging when the systems are non-linear
and/or their interactions with the enviroment are strong.
The contexts in which we ask these questions are extremely varied, and
our approaches eclectic. We are interested in the equilibirum and
nonequilibrium statistical mechanics of nonlinear classical and quantum
systems. We deal with a variety of phenomenological stochastic models in
which nonlinearity and fluctuations coexist, and in which this coexistence
leads to interesting phenomena that would not arise but for the complex
interplay. We deal with reaction-diffusion (and subdiffusion and
superdiffusion) systems and associated pattern formation problems, with
models of phase syncrhonization of noisy oscillators, and with optimal
search strategies. We are
interested in signal propagation in nonlinear thermal arrays. We work
on signal propagation and equilibration in granular matter, transport on
surfaces, hypersensitive response.
Our approaches to these problems combine analytic and numerical methods.
The best way to get a more detailed idea about our work is to
look at the titles and abstracts of some of our
Selected Publications
